Abstract
A numerical simulations of nonlinear pulse propagation in air to elucidate the physical mechanism of the phenomenon are presented. The comprehensive model propagation in air includes the effects of self-focusing (SF), multiphoton absorption (MPA), group-velocity dispersion (GVD), and absorption and defocusing due to the generating electron density. From the simulations experiment, a very dynamic picture emerges of long-distance propagation in which pulses form, are absorbed, and subsequently are replenished by new pulses, thereby creating the illusion of one pulse of energy much less than the input which is self-guided.
